Blind transport format detection in spread spectrum receivers

摘要

The present invention is related to a blind transport format detection method for detecting the transport format of a spread spectrum signal, comprising the steps of: initialising a signal path cost threshold value to a predetermined value D, calculating the signal path cost for the minimum end bit position comparing it to the threshold value, and in case the signal path cost is lower or equal to the threshold value the method further comprises after the comparing step a signal validation step, and the step of setting a valid end bit position variable to the current end bit position nend, and repeating the steps of calculating, comparing and optionally validation and valid end bit position variable setting for incremental values of end bit position until the maximal end bit position is reached, characterised in that the method further comprises the step of setting the threshold value to the calculated signal path cost in case the signal validation step is successful and before incrementing the end bit position. <IMAGE>
